Summary Introduction

To determine:

The function of skeletal system is

  1. Support

  2. Hematopoietic site

  3. Storage

  4. Providing levers for muscle activity

  5. All of these

Answer to Problem 1MC

Solution:

(e) All of these: The function of the skeletal system is to provide lever to the muscles. Bones are the hematopoietic sites. They store nutrients and support the body.

Explanation of Solution

Explanation/ Justification for the correct answer:

The skeletal system in humans consists of 206 bones and a network of tendons and ligaments. The main functions of this system include the movement, support, protection, formation of various blood cells as well as the storage of calcium and other nutrients in the matrix, and endocrine regulation by releasing the hormone known as osteocalcin. Thus option (e) is a correct option.

Explanation for the incorrect answer:

Option (a) is given as support is the function of skeletal system. Skeletal system performs a number of functions like support, protection, formation of various blood cells, storage of nutrients and lever to the muscles. Here, only support is mentioned as a function of skeletal system, thus this option is considered as incorrect option.

Option (b) is given as skeletal system is a hematopoietic site. Skeletal system performs a number of functions like support, protection, formation of blood cells (hematopoietic site), storage of nutrients and lever to the muscles. Here, only hematopoietic site is mentioned as a function of skeletal system, thus this is considered as incorrect option.

Option (c) is given as storage is a function of skeletal system. Skeletal system performs a number of functions like support, protection, formation of various blood cells, storage of nutrients and lever to the muscles. Here, only storage is mentioned as a function of skeletal system, thus this is considered as incorrect option.

Option (d) is given as providing levers for muscle activity is a function of skeletal system. Skeletal system performs a number of functions like support, protection, formation of various blood cells, storage of nutrients and lever to the muscles. Here, only providing levers for muscle activity is mentioned, thus this is an incorrect option.

Conclusion

Thus it is concluded that skeletal system perform a number of functions such as support, protection, formation of various blood cells, storage of calcium and other nutrients and also provide lever to the muscles.

For each of the following problems calculate the following: (Week 6-3 Video with 6-1 and 6-2) Consult the total catabolic pathways on the last page as a reference for the following questions. A. How much NADH and FADH2 is produced and fed into the electron transport chain (If any)? B. How much ATP is made from oxidative phosphorylation (OP), if any? Feed the NADH and FADH2 into the electron transport chain: 3ATP/NADH, 2ATP/FADH2 C. How much ATP is made by substrate level phosphorylation (SLP)? D. How much total ATP is made? Add the SLP and OP together. 1. Aerobic respiration using 0.5 mole of glucose? NADH FADH2 OP ATP SLP ATP Total ATP Show your work using dimensional analysis here:
Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…
